Direct Torque Control Strategies for Interior Permanent Magnet Synchronous Motors Driven by a Three-level Simplified Neutral Point Clamped Inverter
(Auckland University of Technology, 2018)The three-level simplified neutral point clamped (3L-SNPC) was first proposed in 1993. Compared to the T-type and NPC inverters, it uses fewer switching devices to generate a multilevel waveform. This makes the 3L-SNPC ... -
Effectiveness of Slippery Liquid Infused Porous Surface in Viscous Drag Reduction in Boundary Layers at Varying Reynolds Numbers
(Auckland University of Technology, 2021)Drag in marine vehicles is unavoidable but a decrease of the drag is always a perused aim. With modern technologies, it is critical to investigate the new opportunities for achieving reduced drag on the marine vessels and ... -
Energy Business Initiative for Distributed Solar Photovoltaic Systems Adoption in Developing Countries: A Case of Uganda
(Auckland University of Technology, 2021)Global trends in energy generation transition reveal increasing acceptance for renewable energy generation technologies. This is not only about the urge for energy independence and security, but also about the increased ... -
A Generalised Model for Assessing the Large-scale Deployment of Residential Energy Management Systems
(Auckland University of Technology, 2021)Large-scale deployment of effective and suitable demand-side management technologies such as residential energy management systems can bring significant technical, social, and economic advantages for households, and ... -
An Investigation Into the Improvement of Obstructive Sleep Apnea Therapy
(Auckland University of Technology, 2021)The upper airway (UA) patency is a critical element of the breathing cycle. Narrowing of the UA causes breathing difficulties that may cause sudden death. Repeated closure of the UA, and subsequent physiological consequences ...
